What modifications needed for using dual WB O2 sensors with MS-II V3?
Can I connect a WB O2 sensor directly to the relayboard?
Where to connect the other one?

Planning to using MS-II and EDIS on a Ford 351C V8.

You need to build an exact duplicate of the O2 sensor circuit shown in the v3.0 board schematic on http://www.megasquirt.info/ms2/pcb.htm

You can build it in the proto area, it's only 2 resistors and a capacitor and doesn't take up much space.

Jumper the input to the new circuit out to any one of the spare pins on the DB-37 (SPR1-4) and the output to JS5 under the processor.

Select "Dual Wideband" in Megatune and you're away.

Hope that helps, Matt.
